With policies both in US and Europe planning for a systematic exploitation of renewable energy on a strategic scale, the stage is all set now for the fuller development of tidal power on a world wide scale.

The results are clear. It is almost $70,000 "better" financially to build a $450,000 ZEH than to build a $400,000 conventionally built home over a five-year period or over any period of time for that matter.

Our proposal is to build a completely new US power system, based 100 % on renewable energy sources. These sources are to be solar photovoltaic and wind energy, plus solar thermal energy, with carbon neutral biomass fuels available in reserve, in highly efficient heat engines used to level loads and for backup.

With no fuel-costs, or toxicity, solar PV technology, largely based on our friend "Silicon" offers a truly sustainable means of powering industrial loads. This marks the threshold for our transition from the "Hydro-carbon Man, to the beginning of the "Silicon Man".

North America may be making up for its reluctance to embrace a legislation-driven approach to transforming the use of energy by wholeheartedly nurturing companies pushing the boundaries of innovation in the sector.
